Notes:
The oxygen transfer coefficient estimated by both sulfite and dynamic methods and some of the rheological properties of fermentation broths derived from the batch cultivation of a mutant of U. maydis in a sugar cane juice substrate, are used in a scaling-up procedure on the basis of the power consumption per volume unit concept. The fluid was of the Binham plastic type; the Np-NRE correlations showed that the modified Reynolds numbers of the flat-blade turbine impellers were low, near to or in the laminar region; the Na-Pg/P relations were established and then used in the calculation regardless of the geometrical dissimilarities of the vessels. A change of scale from 5 to 50 liters was calculated and operated keeping the power per volume value constant. Reproduction of lysine yields, 2.5-3.2 g/liter, was repeatedly reached in 8 successive runs.
